[Linuxptp-users] Hardware timestamping with bridge device?

[Thomas M. <tm....@gm...>]

Hi everybody,

for a project I have to synchronize around 3 or 4 devices. Because all 
devices have two ethernet ports, one requirement is not to use a 
separate network switch. Instead the idea is to chain up all devices and 
use the middle device(s) as bridge(s).

Example:

DEV1_eth0|DEV1_eth1 <--> DEV2_eth0|DEV2_eth1 <--> DEV3_eth0|DEV3_eth1

I have already tried a few things, but it seems that it's not possible 
to use hardware timestamping with a bridge device.

Has anybody tried to build something like this and can give me a little 
help?


Thanks,
Thomas
